BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a toilet, and more particularly to a water-saving toilet with a certain base to match with a flushing structure, obtaining a water-saving purpose.

2. Description of the Prior Art

Saving water source is an important environmental friendly issue for people. Therefore, a water saving purpose is constantly improved by toilet's manufacturer when using the toilet to urinate and flush the urine.

However, such a water-saving toilet still has the following defects:

-   -   1. As flushing urine, three liters of waters are used, but such         a flush quantity is greatly more than that of the urinal (i.e.,         one liter of water).     -   2. The water-saving toilet includes a two-section flushing         structure, yet such a two-section flushing structure is easy to         be broken in a long period of time, causing a replacement         trouble.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a water-saving toilet that is capable of obtaining a water-saving purpose.

Further object of the present invention is to provide a water-saving toilet so that while pressing the flush button, a suitable water flows out of the outflow holes of the first and the second flow pipes in turn to flush the cavity simultaneously, thus obtaining a cleaning purpose.

Another object of the present invention is to provide a water-saving toilet that while water flushes into the U-shaped tube, the dirty fluid in the U-shaped tube is flushed outward and only little water is left to achieve water-saving and cleaning purposes.

To obtain the above objective, a water-saving toilet provided by the present invention contains:

-   -   a base including a cavity formed therein, an outlet disposed on         a bottom end of the cavity, a U-shaped tube communicating with         the outlet, a cushion fixed on an upper portion of the base, a         stopping member secured on an upper end of a back side of the         base, and a flush button arranged on the stopping member;     -   the stopping member including an inlet pipe disposed on an upper         end of an inner space thereof to connect with a first flow pipe         and a second flow pipe, both of which are fixed in the upper         portion of the base, the first and the second flow pipes         respectively including a plurality of outflow holes to flow         water outward;     -   wherein lengths of the first and the second flow pipes are equal         to flow the water at the same speed, wherein when flushing the         water, the water flows from the stopping member to the cavity         via a first predetermined section of the first flow pipe without         the outflow holes, and on a second predetermined section of the         second flow pipe relative to a third predetermined section of         the first flow pipe with the outflow holes is not provided with         the outflow holes so that the water flowing toward a distal end         of the first flow pipe further flows into the stopping member         via the outflow holes of the first flow pipe.
